The 2016 Green Party presidential primaries were a series of primaries, caucuses and state conventions in which voters elected delegates to represent a candidate for the Green Party's nominee for President of the United States at the 2016 Green National Convention. The primaries, held in numerous states on various dates from January to July 2016, featured elections publicly funded and held as an alternative ballot, concurrent with the Democratic and Republican primaries, and elections privately funded by the Green Party, held non-concurrently with the major party primaries. Over 400 delegates to the Green National Convention were elected in these primaries, with a candidate needing a simple majority of these delegates to become the party's nominee for president.
